Inspired by the Segway personal transporter, Miguel Ángel de Frutos has demonstrated his robot that operates in a vertical fashion balancing on two wheels - his "Vertibot". Although the concept seems somewhat complex, Miguel has explained the required electronics as well as the physics theory related to the balancing. By using a "six degrees of freedom" sensor board and measuring the results every 10 milliseconds the robot can balance quite well, as shown in the demonstration video below:
It's a fascinating and educational project, that could be scaled up if necessary, so review Miguel's website (opens in Google Translate) for the details. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
